Precalculus book,your opinion is needed.

[YYaaSSeeRR]

hi
I have graduated from high school and now I am going to apply to Cleveland state university to study Electrical engineering.
anyway,I will have about 5 months before starting classes so I will need to strength my math foundation for calculus.
I bought Precalculus for dummies but I figured out it gives you superficial information so I decided to use another book.
I have found this one:
Precalculus (an investigation of functions) ,it is a free book and here is the website:

I would appreciate it if you make a look and tell me what do you think.

I would appreciate it if you have any other recommendations.

I haven't seen this book, but it seems to cover the common topics. I can really only suggest the one that I used, which was Precalculus with Limits by Larson. I don't remember it being phenomenal, but it got the job done. I know that Stewart has one too, of which I haven't heard complaints. Generally, if it's written by a calculus author, he is exposing precalculus with calculus in mind.
